"I recommend Dennis (Harmon & Harmon) in the strongest terms for a renovation, upgrade, or any other construction in your home. I hired Harmon & Harmon for some upgrades/repairs in a home I recently bought, including a major renovation of my attic (dark, unfinished space, bare studs) to be a fully finished room. Dennis saw the potential of the attic (which was huge & very open). Now fully finished, the attic has a beautiful composite wood-grain floor, finished walls, recessed lighting, full climate control with a mini-split, and he was even able to add a window with a view to the water. It is a huge room that now functions as a TV room for the kids with a big sectional couch, one corner is an extra closet/storage nook for my wife, & the gabled window area has table & chairs for reading and enjoying the view. Best thing about Dennis... 100% follow-through, 100% satisfaction. If I had an issue, he fixed it, period. Outstanding professionalism from start to finish. A+, 10/10!"

Koi Construction, LLC, originally established as HK Design & Remodeling and M&I Property Services, has always started from modest beginnings. Our core belief is that true success comes from engaging passionately in our work, rather than being driven by financial motives. We are committed to excelling in our projects, making a distinct mark through exceptional performance. Our unwavering focus remains on outstanding client service and superior craftsmanship. Despite our growth, we steadfastly adhere to our fundamental mission: "To achieve ongoing success by ensuring client satisfaction, delivering high-quality services, and upholding genuine integrity, all of which culminate in the finest craftsmanship."

"The whole experience was excellent. Chris when to give us a bid. He was very knowledgeable. He told use about the triangle of stove, fridge and sink and flow. He suggested a long narrow window to replace the tile backsplash on an outside wall. It was a great idea. When sit at the new bar between the kitchen and the living room we look out into our backyard. Itâ s beautiful. The guys that did the work are extremely work oriented. They are constantly working. They were thorough, knowledgeable and open to our suggestions and requests. We wanted an additional can light no problem. They were great. They cleaned up every day before they left. They would tell use when they were going to arrive and what they planned to accomplish that day. I have old siding on the outside of my house. They matched it perfectly when eliminated a window. The price of the cabinets was a lot more reasonable the other bids and theyâ re beautiful. What I mentally pictured in my mind on how it would look and the ease of preparing meals in the new kitchen were so wrong. Itâ s at least 10 times better. It still has the same physical dimensions but how itâ s played out. It seems so much bigger. I highly recommend them for any project you need done"

License and bonded subcontractors are used in new construction and major re-models. We offer free estimates, and prefer to work with our customers in all design work. We have an excellent line of reasonably priced cabinets and granite counter tops. We are customer oriented and aim to please.

"Jared and his team did an amazing job. From start to finish, it was clear they wanted to make sure we got what we wanted. Jared worked with us to come up with the design, and the team were all great to work with. They continuously kept us informed of what they were doing, and if something needed adjusting after it was done, they were very quick to make any requested changes. The job included removing a window, and re-sizing two others; replacing siding on the exterior and matching our existing paint; re-sizing the living room archway; replacing kitchen and bath flooring with tile; removing a bathtub, re-arranging the bathroom and adding a large shower; moving a tankless water heater from outside to inside; re-routing gas and water for the washer and dryer; installing new appliances; installing cabinets and quartz countertops. I highly recommend this company and will be hiring them again for future projects."

Are you looking for home improvement or bathroom remodeling advice? Luxury Bath is privately owned and been in business for over 15 years. It is the number one trusted resource for customers looking to update their bathroom or have a complete bathroom remodel. If you’re wanting advice on how to make your bathroom larger, how to remodel on a budget, or even looking for a local bathroom remodeler, Luxury Bath has the answers to all your remodeling questions. Open showroom available in Redmond too!!!!

"Don't work with Luxury Bath of Seattle!! Contacted Luxury Bath about remodeling two bathrooms at my property. Carlos Bezerra, Director of Operations, came to provide the bid. He diverted the work to his own company, Handy Buddy LLC, after indicating it was part of Luxury Bath. Corresponded with me via the entire project using his Luxury Bath e-mail. The project required significant rework and I had to finish a portion because he wouldn't fix some final items. 2 years later the work performed failed and I am now in the process of having it redone by a different contractor. Attempted to speak with Luxury Bath of Seattle owner, Raz Gunderman, numerous times. However, he has avoided all my attempts at communication. I have now had to obtain a lawyer to pursue a refund. Extremely dissatisfied."

"I wanted a sturdy shed built on my poured concrete slab. I knew how large I wanted it, but after that, I needed help. Nate worked with me to design, build and finish my 12x16 shed from start to finish. The process was efficient, and the shed is beautiful. Honestly, what I call a shed, would probably classify as a garage, had we installed a garage door, but that was not what I needed at the time. While working with Nate, I quickly recognized he could be trusted to find a solution to any problem. Next he helped me plan and built a matching railing for my home’s staircase, after I had previously removed an old rotting one. Again, this process was quick easy and friendly. Sadly I moved away from the area, but if I ever return, I will always reach out to Nate first for my building and remodeling needs."

FAQs for addition to existing structure building service projects in Tumwater, WA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
